Answer
a. 145.5 million
b. 2010
c. (0, 146.1) In the year 2000, the population of Russia was ~146.1 million.
d. Domain = [2,9]; Range = [141, 145]
Work Step by Step
a. $x=2001-2000=1$
When x is 1, y is approximately 145.5 million, thus making the population of Russia in 2001 ~145.5 million.
b. $y=140$
When y=140, x is approximately 10.6, so the year would be 2010 when the population is about 140 million.
c. When x=0... y=~146.1 or (0, 146.1) so the population in 2000 was ~146.1 million.
d. Since the data seems pretty reliable, I would say that the domain would be in between the years 2002 - 2009, making the domain = [2,9]. By using this domain, I get a range of 141 million - 145 million, making the range = [141,145].
